Optimizations

See merge request !2

Some optimizations to speed up importing messages. Speed up is 2x, from 400 sec to 200 sec to import 10k messages, on local pod.

General idea is to:

* Use `set` instead of `list` when we check for existance of items.
  * This requires that `Item` is hashable, which is not. So I patched schema items with `__hash__` function and used `external_id`s as hashes, which should be unique anyway.
* Use `lru_cache` when querying item by id, so we don't have to wait for pod to respond.
